Stamatis Zampetakis reassigned HIVE-24438: ------------------------------------------ > Review shutdown hooks for memory leak > ------------------------------------- > > Key: HIVE-24438 > URL: https://issues.apache.org/jira/browse/HIVE-24438 > Project: Hive > Issue Type: Task > Reporter: Stamatis Zampetakis > Assignee: Stamatis Zampetakis > Priority: Major > > Shutdown hooks cannot be garbage collected till the JVM shutdown making the > application prone to memory leaks. In many cases shutdown hooks are > registered through the use of an anonymous class. If the class is created > from non-static context then the hook implicitly holds a reference to an > enclosing instance that is not always desirable and can lead to memory leak. > The goal of this issue is to review calls registering shutdown hooks and > eliminate any reference to enclosing instances if that is possible. > Check the callers of: > * ShutdownHookManager#addShutdownHook(java.lang.Runnable) > * ShutdownHookManager#addShutdownHook(java.lang.Runnable, int) > -- This message was sent by Atlassian Jira (v8.3.4#803005)
